Hi Doug,
Use 1/8 6011 or 6010 with enough amps that the rod starts easy. Using the back step method while using a close arc length, deposit a molten puddle then whip the rod back allowing the puddle too slightly cool then move the rod back in to 1/2 rod diameter and once again deposit molten metal, repeat for 1/2 long weldments.
while using a #9 lens, If the base metal looks red, then your fixing too burn a hole. Lift the arc and pause for a few seconds then continue.
Don't waste your time with 6013 or 7018 as the flux is too heavy and the electrode will be hard to start.
For a inexperience weldor, using 1/16 or 3/32 will cause more frustration than using 1/8 as the rod will be easy to stick.
You can also look on the Tool forum archive as I've written several articles on how to weld SM.
